- First, then, what about neutron decay?
- In another analytical method, neutron activation, an atomic reactor is used to bombard the mineral with fast-moving neutrons.
- Quarks unite to form protons, neutrons and electrons, which in turn unite to form atoms.
- Then they saw Jones' underground laboratory, the neutron spectrometer and its data, which were much more extensive than theirs.
- These stars would be supported by the exclusion principle repulsion between neutrons and protons, rather than between electrons.
- They were therefore called neutron stars.
- This is about a factor of 3 smaller than current best estimates of the neutron star radius.

COLLOCATIONS FROM OTHER ENTRIES► a neutron bomb
a part of an atom that has no electrical charge (=that kills people but does not damage buildings much)
COLLOCATIONS FROM THE CORPUSNOUN► activation· This is where neutron activation analysis enables us to source them with certainty.· He has his forensic pathology run-down, his neutron activation analysis.· Analytical techniques such as atomic absorption spectrophotometry and neutron activation analysis may be required for quantitative determination at such low levels.· In another analytical method, neutron activation, an atomic reactor is used to bombard the mineral with fast-moving neutrons.· Quarried blocks of marble and finished sculptures have been analysed by neutron activation and the results have been very encouraging.· One of these techniques is neutron activation analysis.· The use of neutron activation analysis is best explained by the following case study.· This dish has a Valencian shape but the crowded design is Malagan; neutron activation analysis shows it to be Valencian.
► bomb· He spent some time expressing his preference, for tactical reasons, for smaller neutron bombs before developing his argument.
► star· This is about a factor of 3 smaller than current best estimates of the neutron star radius.· Despite such small size, a neutron star can contain as much mass as 500, 000 Earthsized planets.· They were therefore called neutron stars.· It is also too large a mass to be a neutron star.· In this context, a neutron star is effectively a single atomic nucleus.· It is highly relevant to ask what values have been measured for neutron star masses; do they fall in with expectation?· In the standard formation model, millisecond pulsars are formed when a neutron star accretes matter from an evolving companion.· Another such state is a neutron star.
► stars· They were therefore called neutron stars.
VERB► produce· But there would be some D-D reactions in a reactor filled with deuterium and helium-3, which do produce neutrons.
