What are the two types of scattering mentioned?

The two types of scattering are elastic and inelastic scattering.

What happens during inelastic scattering?

During inelastic scattering, the nucleus goes into an excited state and may later emit radiation.

What are the different types of absorption processes?

The types of absorption processes include electromagnetic absorption, charged particle absorption, and neutral absorption.

What particles might be emitted during charged particle absorption?

During charged particle absorption, the nucleus can emit particles like alpha particles or beta particles.

What could result from the absorption of a neutron?

Absorption can lead to the emission of particles such as neutrons, alpha particles, beta particles, or high-energy photons.

What can cause fission in neutron interactions?

Fission can occur if the neutron has sufficiently high energy to break apart the nucleus.

What can uncontrolled fission reactions lead to?

Uncontrolled fission reactions can lead to a fission bomb.

Which particle interacts more with the neutron, the nucleus or the electron?

The neutron is more likely to interact with the nucleus due to its larger cross-section compared to the electron.

What kind of radiation can be emitted from electromagnetic absorption?

Electromagnetic absorption can emit photons or high-energy photons such as gamma rays.

Zusammenfassung

TLDRThe video by Walter discusses how neutrons interact with matter, specifically focusing on the interactions with the nucleus of an atom. When a high-energy neutron interacts with a nucleus, either scattering or absorption processes can occur. In scattering, there are two types: elastic, where kinetic energy is conserved, and inelastic, where the nucleus enters an excited state and later emits radiation. Absorption involves the neutron being absorbed into the nucleus, and various products may be emitted depending on the type of absorption. Absorption types include electromagnetic, charged particle, and neutral, each emitting different radiation such as photons, alpha or beta particles, or more neutrons. Furthermore, if a neutron has enough energy, it can cause fission, breaking the nucleus into smaller fragments and possibly leading to an uncontrolled reaction akin to a fission bomb. The likelihood of a neutron interacting with the nucleus is higher than with orbiting electrons due to the nucleus's larger cross-section.

Walter discusses neutron interactions with matter, focusing on how neutrons interact with atomic nuclei rather than electrons. He describes that interactions result in either scattering or absorption. Scattering can be elastic, where the kinetic energy is conserved, or inelastic, leading to energy release later. Absorption involves the neutron being absorbed into the nucleus, with possible emission of particles or radiation, including fission, where the nucleus splits and releases more neutrons and radiation—a process central to nuclear bombs.

00:00:05
hello my name is Walter in glob and this
00:00:08
is Neutron interactions with matter when
00:00:11
we consider a neutron interacting with
00:00:13
matter what we typically consider is a
00:00:16
neutron interacting with the nucleus of
00:00:20
an atom so here I have an atom with one
00:00:25
or more electrons orbiting the nucleus
00:00:27
and I have a neutron like a high-energy
00:00:30
neutron that comes in and interacts with
00:00:35
this nucleus there's several things that
00:00:37
can happen depending on this particular
00:00:40
trajectory and the energy of the neutron
00:00:42
and this particulate nucleus that we're
00:00:45
considering we can either have
00:00:48
scattering processes or we can have
00:00:55
absorption occur
00:01:01
if we first focus on scattering there's
00:01:03
two types of scattering events that can
00:01:05
occur either the collision process will
00:01:09
be elastic meaning that the total
00:01:12
kinetic energy between the two particles
00:01:14
is conserved or we can have inelastic
00:01:20
scattering and what happens here is that
00:01:25
the nucleus will go into an excited
00:01:27
state due to the momentum the energy
00:01:31
that this incoming Neutron had and at a
00:01:33
later point in time the nucleus can emit
00:01:37
some radiation due to the D excitation
00:01:41
after the inelastic scattering event has
00:01:45
occurred if we consider absorption that
00:01:49
means that the neutron is absorbed into
00:01:52
the nucleus and there are many different
00:01:54
types of absorption processes that can
00:01:57
occur in this type of interaction for
00:01:59
one we can consider electromagnetic
00:02:04
absorption or a charged particle
00:02:10
absorption or neutral absorption and
00:02:15
each of these types of processes involve
00:02:19
the neutron being absorbed into the
00:02:21
nucleus and then some other type of
00:02:23
particle being emitted from the nucleus
00:02:26
so if it's neutral that means another
00:02:30
neutron has been emitted from the
00:02:33
nucleus for a charged particle type of
00:02:37
absorption the nucleus can emit
00:02:40
different types of radiation like alpha
00:02:43
particles or beta particles and then
00:02:45
electromagnetic radiation from the
00:02:48
absorption of the neutron can involve
00:02:50
for example photons or high in
00:02:55
high-energy photons such as gamma rays
00:02:58
so
00:03:00
here we can have a positron or an
00:03:03
electron and a final type of absorption
00:03:09
would be fission so if the neutron is of
00:03:13
high enough sufficient energy then it
00:03:17
can break apart this nucleus and the
00:03:21
nucleus will break up into daughter
00:03:22
products and not just smaller nuclei but
00:03:27
probably other radiation such as gamma
00:03:31
rays or positive positive or and even
00:03:36
another Neutron and if this continues on
00:03:40
with many nuclei then you can have an
00:03:43
uncontrolled fission reaction and that's
00:03:45
what a fission bomb is so these are the
00:03:48
different types of interactions that a
00:03:51
neutron can have with matter
00:03:54
specifically the nucleus and the nucleus
00:03:57
will have a larger cross-section
00:04:00
compared to the electron meaning that
00:04:02
the probability of the neutron hitting
00:04:04
and interacting with the nucleus is
00:04:06
larger than that of the neutron
00:04:08
interacting with the electron orbiting
00:04:11
the nucleus my name is Walter une glove
00:04:14
and this is Neutron interactions with
00:04:16
matter
