Abstract
Abstract A liquid scintillator solution which consists essentially of a polyalkylene glycol derivative of the formula: ##STR1## wherein R 1 to R 5 are each a hydrogen atom, a straight chain or branched chain alkyl group having 1 to 10 carbon atoms or a cyclohexyl group, R 6 and R 7 are each a hydrogen atom or a methyl group provided that both R 6 and R 7 are not methyl groups, m is 0 or 1 and n is a value between 2 and 15; and a scintillator.

A liquid scintillator solution which consists of a polyalkylene glycol derivative of the formula: ##STR18## wherein R 1 to R 5 are each a hydrogen atom, a straight chain or branched chain alkyl group having 1 to 10 carbon atoms or a cyclohexyl group, R 6 and R 7 are each a hydrogen atom or a methyl group provided that both R 6 and R 7 are not methyl groups, m is 0 or 1 and n is a value between 2 and 15; and a scintillator.
Claim 2
Dependent Claim
87 words
A liquid scintillator solution which consists of a polyalkylene glycol derivative of the formula: ##STR18## wherein R 1 to R 5 are each a hydrogen atom, a straight chain or branched chain alkyl group having 1 to 10 carbon atoms or a cyclohexyl group, R 6 and R 7 are each a hydrogen atom or a methyl group provided that both R 6 and R 7 are not methyl groups, m is 0 or 1 and n is a value between 2 and 15; and a scintillator.
Claim 3
Dependent Claim
33 words
The liquid scintillator solution of claim 1 in which as the scintillator a first solute is present in an amount of about 3 to 10 g per liter of said polyalkylene glycol derivative.
Claim 4
Dependent Claim
54 words
