Neutron-capture prompt-gamma activation analysis (PGAA) is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with ...

with elements heavier than this being created via the s-process (slow neutron capture) or r-process (rapid neutron capture), which may occur during supernovae. This is how the majority of known ...

The researchers believe ASKAP J1839-075, is a "pulsar", a high-energy neutron star that releases short bursts of radio waves. But conventional wisdom is that when pulsars slow down they stop ...
