Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_68765 ( "Group" real, "Half-Life (s)" real, "Decay Constant (s \u22121 )" real, "Yield, Neutrons per Fission" real, "Fraction" real )

### Question ###
What is the lowest Half-Life with a Yield, Neutrons per Fission greater than 0.0054600000000000004 and a Fraction less than 0.002568?

### Accurate SQL ###

SELECT MIN("Half-Life (s)") FROM table_68765 WHERE "Yield, Neutrons per Fission" > '0.0054600000000000004' AND "Fraction" < '0.002568'
