Reminders adopted

Adopted Properties

Q-record – must be given -even if nothing

known

Values from Audi masses, explanation if from other source, give Audi values for comparison

Give Systematic uncertainties as comments.

Reminders-Adopted


Reminders adopted1

Adopted Properties

XREF even if only one data set with gammas

BAND Identification only on first record

Reminders-Adopted


Reminders adopted2

Adopted Properties

Levels:

GS and Isomers: Decay Modes and moments must be given, if known, on the continuation records. Any comments on these should be on the comment records only.

T1/2 from keyno. Is not enough, include DSID

Moments – Check Stone’s compilation (2005St25)

Isomer is a level with T1/2>=0.1 S or if it has an IT dataset

Reminders-Adopted


Reminders extraction of data

Quote authors’ measured quantities

Document any deviations

Note authors’ assumptions

Check for missed references

Check authors’ quoted older values

Reminders-extraction of data


Reminders presentation of data 1

Order of Comments

E= not needed for reaction

Target JPI should be given

Keyno: measured, etc.

Do not combine different kind of data sets

Specify source of data

Ensure accuracy of values from adopted set

Do not say “from ENSDF”

Reminders-presentation of data-1


Reminders presentation 2

Gammas order by increasing Eg

Significant digits

Uncertainty limited to 25

Multiplets

Xsection,Analyzing-power not given

A2, A4, DCO ratios given with definition

Reminders-presentation-2


Reminders presentation 3

BEL up for levels, down for gammas. Program modified

Delayed gammas - give as IT decay, ex 140Dy

Reminders-presentation-3


Reminders presentation 4

Normalization condition should be given

Parent record, all fields should be given

Replace `/’ by `:’ for multiple ratios

Unresolved discrepancies should be pointed out

Uncertainty not error

E(ec),E(b-) only when accurate, measured

XUNDL data helpful but evaluator responsibility

Reminders-presentation-4


Reminders systematics

LogT1/2(alpha) vs Log E(alpha) is linear

Takahashi’s gross beta decay theory reliable to better than a factor of 3

Alpha Decay HF

Certain pairs of conf lead to isomeric transitions

GS feeding from local systematics

Mass syst from Audi

Reminders-Systematics


Reminders style

APS style adopted

Accepted abbreviations

Key no. is plural. Space after `,’ etc.

Reminders-Style
