“…A t times, some of t h e s e unwanted r a d i a t i o n s can be eliminated by c o i n c idence techniques o r h i g h -r e s o l u t i o n apparatus. Nelson and Hatch (18,19) employed a b e n t -c r y s t a l spectrometer t o measure K x-ray t o gamma-ray r a t i o s i n t h e decays of ~m '~' , Ho 166 and ~u~~~' : Boneau and Hatch (20) used a normal NaI(T1) s c i n t i l l a -' , t i o n c r y s t a l i n a coincidence arrangement t o measure a~ f o r a t r a n s i t i o n i n ~r~~~ by t h i s method.
